* macosx/tkMacOSXWindowEvent.c (Tk_MacOSXIsAppInFront): use process mgrcore_stablilizer_merge
* macosx/tkMacOSXMouseEvent.c: to determine if app is in front instead of relying on activate/deactivate events (which may arrive after this info is needed, e.g. during window drag/click activation); replace other process mgr use to get this info with calls to Tk_MacOSXIsAppInFront(). * macosx/tkMacOSXMouseEvent.c (TkMacOSXProcessMouseEvent): correct window click activation, titlebar click handling and background window dragging/growing in the presence of grabs or window-/app-modal windows; fix window click activation bringing all other app windows to front.
